1) About how long ago did the big bang take place?
13.7 billion years ago
2) What is a black hole?
Black holes are areas of intense gravitational pressure.
3) Does the universe continue to expand?
expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe.
4) Was there really a big bang?
No because we tend to imagine a giant explosion. Experts however say that there was no explosion; there was (and continues to be) an expansion.
5) What light elements seem to support the Big Bang Theory?
Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins.

4.6 years 15) What are time zones?
Given a 24 hour day and 360 degrees of longitude around the earth, it is obvious that the world's 24 time zones have to be 15 degrees wide, on average. The individual zone boundaries are not straight, however, because they have been adjusted for the convenience and desires of local populations.
